FDD massive MIMO with analog csi feedback

2015 49th Asilomar Conference on Signals, Systems and Computers, 2015
Massive multiple-input multiple-output (MIMO) is a breakthrough in cellular networking, through using a large number of antennas to serve simultaneously many users. Most prior work on massive MIMO assumes time-division duplex (TDD) operation to take advantage of channel reciprocity.

Deep Learning-Based Massive MIMO CSI Feedback

2019 18th International Conference on Optical Communications and Networks (ICOCN), 2019
Massive multi-input and multi-output technology is a key technology for future 5G wireless communication. The channel feedback problem of massive mimo becomes more and more challenging as the size of the mimo channel matrix becomes larger. A supervised deep learning-based encoder-decoder scheme was proposed to improve recinstruction quality recovery ...

Optimized CSI Feedback for Robust THP Design

2007 Conference Record of the Forty-First Asilomar Conference on Signals, Systems and Computers, 2007
In the broadcast channel (BC), the signals of the multiple users can be separated by means of preceding. For the design of precoding, channel state information (CSI) is necessary at the transmitter side. In many cases (e.g., for frequency division duplex (FDD) systems), the transmitter cannot estimate this information and the CSI has to be communicated

Power Allocation without CSI Feedback for Decision-Feedback MIMO Signal Detection

2007 IEEE Wireless Communications and Networking Conference, 2007
Transmit and receive antenna arrays can be used to form multiple-input and multiple-output (MIMO) systems for improving the reliability and capacity of data transmission. Layered space-time coding with decision-feedback detection is a promising technique for future wireless communications.

LMS for Truncate CSI Feedback in Massive MIMO

2019 International Conference on Computing, Electronics & Communications Engineering (iCCECE), 2019
In this work, a new methodology for estimation of channel state information (CSI) is presented dependent upon the idea of Least Mean Square (LMS). The strategy is formed to massive MIMO frameworks through feedback communications. The technique is intended to reduce the amount of feedback communication information contains in the CSI data block from the
